Photos: Atlas V Rocket Assembly for Space Station Cargo Run

A United Launch Alliance Atlas V 401 rocket takes shape at Space Launch Complex 41, Cape Canaveral Air Force Station for an April 2017 launch with the Cygnus OA-7 spacecraft on a critical resupply mission to the International Space Station. Assembly of the two-stage rocket started with the rollout of the Common Core Booster and its installation atop the Mobile Launch Platform before the Centaur Upper Stage, already integrated with its interstage and forward adapters was hoisted to complete the stack.
